Solar Generation Facility & Collector Substation

Our team supported a 55-megawatt (MW) solar generating facility project in the Pacific Northwest. The project added renewable generation capacity to the region and interconnected with a regional utility’s 230-kV transmission system.

Burns & McDonnell, AZCO’s parent company, was the engineering, procurement and construction contractor, with AZCO performing solar field equipment installation and construction. The project scope included construction of the solar generating facility and a new collector substation to support delivery of renewable energy to the utility transmission system.

We also supplied, fabricated and delivered 25 tons of standard shape substation steel for the project’s collector substation. Standard shape steel includes common structural members such as beams, channels, angles, plates and pipe fabricated to meet project-specific drawings, tolerances and connection requirements. These steel components provide support for critical substation infrastructure, including equipment, bus work, switches and insulators.

Our fabrication team measured, cut, drilled, fit-up, welded, inspected and prepared each steel component for field installation. Accuracy and quality control were essential, as substation steel must align properly with electrical equipment and other structural components during installation. By completing this work in a controlled fabrication environment, we helped reduce field labor demands, limit installation risk and support a safer, more efficient construction process.

Through its combined field construction and fabrication capabilities, AZCO helped advance the project schedule, improve constructability and support the successful buildout of the solar facility and its substation interconnection infrastructure.
